CLRS Series RS485 Closed Loop Stepper Drive User Manual
1 Introduction
1.1 Product Introduction
CLRS Series are closed loop stepper drive based on standard Modbus RTU protocol, using RS485 communication
can network up to 31 axes, built-in 16-segment position table (PR Mode --Position Register mode ). They can not
only solve the problem of step loss in the open loop stepper system, but also can save additional controllers in most
of point-to-point applications, to greatly enhance system reliability and reduce the cost. CLRS Series also support
the feature of teaching, the operation modes of Profile Position, Profile Velocity and Homing. They can power 2-
phase NEMA 8, 11, 14, 17, 23, 24, 34 stepper motors with 1000 ppr to 5000 ppr incremental encoders.
The CLRS series is highly reliable and affordable and performs excellently in many industrial applications such as
solar equipment, textile, civil, robotics, power generation equipment, 3C, packaging...

Compare with Step/Direction
Built-in single-axis control can save the PLC in most of point-to-point applications to reduce
cost;
Built-in rich diagnostic functions and input and output signals to setup easily;
Modbus brings more expansion possibility to add value;
1.3 Application Scenarios
Divided into simple hands-on tuning and practical application scenarios

drive and motor,
as described in
Section 6.1
(2) Simple motion can also be performed with serial port tools, which requires
General serial port tools software,
RS485 tuning cable (User-provided), RS485toUSB converter, drive and motor,
as described in
Section 6.2
.
